Abstract
PURPOSE:To increase additional value for sound energizing function, by arranging >=2 speakers having different reproducing frequency bands at sound energizing section arbitrarily. CONSTITUTION:At upper part of a digial watch 11, micro-speakers 13, 13' of electromagnetic type or piezoelectric type driven by a rectangular wave signal or triangle wave signal are arranged. Since left and right speakers 13, 13' have different reproduction frequency band, the broad band reproduction is enabled and also the resolution of scale is increased by using one for accompaniment and another for main melody. Further, through the combination of song voice, main melody, voice and music, a portable small-sized sound producing device having rich variety, doubled amusement and high additional value together with clear composite sound can be realized.
